Title: Improvements in and relating to printing machines
IPC: B41F13/28
Filed: 1934-01-31
Abstract: 412,143. Printing-machines. POLLAK, J. E., 20, Holborn, London.-(Multigraph Co. ; 1840, East 40th Street, Cleveland, Ohio, U.S.A.) Jan. 31, 1934, No. 3260. [Class 100 (ii).] Tripping - arrangements.-In a printing- machine one of the printing-members such as the impression roller 17 is mounted on an eccentric shaft 16, one of the journals 15 of which is fitted with an operating handle, e.g. a knurled knob 21, which is mounted on the journal 15 so as to have a loose play thereon and is adapted where operated to release a lock which normally holds the shaft 16 in a position to maintain the printing-members in operative position. After the lock is released, continued movement of the knob rotates the shaft 16 so as to relieve the printing pressure. The handle 20 is mounted between a collar 30 fixed to the journal 15 and a washer 23 secured to the journal by a screw 24. The locking- member consists of a latch 33 pivoted to the collar 30, and it normally engages a groove 18 in a plate 40 which can be set in variable positions so as to enable the printing pressure to be adjusted. To release the lock the handle 20 is rotated clockwise, and a pin 41 engages a bevelled portion 34 of the latch 33 and depresses the latch against the action of a spring 35. The pin 41 finally transmits motion to the collar 30 and the shaft 16. The rotation of the handle 20 is limited by a stop 46 so as to prevent the shaft 16 from being rotated far enough to bring the printing members back into operative position. On the reverse movement of the handle 20 a pin 41<a> returns the shaft 16 back into printing position, and the latch 33 locks automatically, or a stop 45 may be provided to arrest the handle in its locking position. As applied to an offset printing-machine, the printing-cylinder 55, Fig. 1, may be controlled by mechanism similar to that described for controlling the impression cylinder 17.

Title: A device for the protection of submerged or buried metallic surfaces from corrosion
IPC: C23F13/04
Filed: 1957-01-31
Abstract: 854,909. Preventing corrosion. COMPAGNIE DE CONSTRUCTION DE GROS MATERIAL ELECTRO-MECANIQUE. Jan 31, 1957 [Feb. 28, 1956], No. 3409/57. Class 123(1) [Also in Group XXXV] Electrolytic corrosion of submerged or buried dissimilar metals forming part of an electrically continuous metallic system, for example, a ship's hull 23 and propeller 20, by corrosion currents set up by the electro chemical potential differences existing therebetween is prevented by connecting a low resistance shunt 26 in parallel with the normal external flow path of the current between a brush 24 bearing on the propeller shaft 21 and the hull, measuring the current flow in the shunt and/or the voltage drop thereacross and applying a counter-voltage to the shunt which prevents current flow therethrough and is also effective to prevent flow in the normal path. The opposing voltage may be regulated manually or automatically by the arrangement shown in Fig. 5, wherein the shunt 26 is shown connected across a resistor 16 representing the normal external current flow path. One end of the shunt 26 is also connected to a point between two batteries 28, 281 serially connected to a potentiometer 29, the slider 30 of which is connected through a regulator 37 to the other end of the shunt. The regulator serves automatically to adjust the slider 30 according to signals received from a voltmeter 36 to maintain zero potential across the shunt and resistor 16 so that no corrosion producing current flows. A switch 33 enables a second shunt 39 and potentiometer 41 having a slider 42 automatically set by a regulator 44 according to signals received from a voltmeter 43 to be placed in circuit to give a fine adjustment of the applied opposing voltage.

IPC: B22C17/10
Filed: 1952-02-08
Abstract: 707,268. Dashpots. ZIMMERMANN MASCHINENFABRIK GES., G. Feb. 8. 1952, No. 3420/52. Class 108(3) [Also in Group XXII] In a turnover moulding machine, the centre of gravity of the turning member is above the axis of rotation at the beginning of a turning movement which, after being started, is controlled and finally halted by a dashpct. During the compacting of the sand by a jarring device (not shown) the turning frame 3 is clamped by a wedge 18, Fig. 4, operated by a piston 16 so that it moves between the bottom of the frame and a fixed wedge member 19. After the release of this clamping means, the turning of the frame from the position shown in Fig. 1 is initiated by a piston 8 secured to a rack 10 engaging the turning pinion 11. The rack is also secured to the rod of a dashpot piston 12, Fig. 3, which moves within a cylinder having symmetrical ports a, b and c so that the effect is the same in whichever direction the piston is moving. At the beginning of its movement the liquid may flow freely through one of the passages a, past a non-return valve 14. When this passage is closed by the piston, fluid may circulate only through passages b and c, which are adjustable by valves 13, and finally only through the appropriate passage c. After removing the mould from the machine, the centre of gravity of the turning frame is again above the axis. In a modification, the turning movement is started by means of a spring.

Title: An improved mixing screw for plastic materials
IPC: B29C48/67
Filed: 1952-02-08
Abstract: 711,875. Mixing appliances. JACKSON & CHURCH CO. Feb. 8, 1952 [Aug. 13, 1951], No. 3434/52. Class 86 [Also in Group V] An apparatus for working a plastic material particularly vinyl plastics includes a screw rotating within a cylindrical chamber to advance the material therethrough, the screw having a helical thread of constant outside diameter with a central section whose root diameter is enlarged with respect to the end sections. The screw rotates within a cylindrical chamber 6 and feeds plastic material from a hopper 8 to an outlet at the end 16 which may be provided with moulds or extrusion dies, not shown. A helical thread 11 of constant lead and constant outside diameter extends along an output portion 3 of the screw and along a centre portion 5 of the screw, the root diameter of which centre portion progressively increases towards its centre. The centre portion 5 has a pair of auxiliary threads 13 and 14 having the same lead as the thread 11. The input portion 4 of the screw has a thread 12 having the same outside diameter and root diameter as the thread 11 but having a somewhat larger lead. The reduction of the cross sectional area presented to the flowing plastic material as it passes from the input portion 4 to the centre portion 5, due to the increase in root diameter and to the addition of the auxiliary threads, causes the plastic material to be squirted through the centre portion at a speed higher than the speed of the surface of the screw over which it moves. The cross sectional area is reduced by a factor :greater, preferably 2 to 6 times greater, than unity divided by the percentage efficiency of the input end portion of the screw, the percentage efficiency being the percentage ratio between the distance the plastic material is advanced by one rotation of the screw and the distance a nut would be advanced by one rotation of the screw. Specification 684,582 is referred to.

Title: Improvements in and relating to sound receivers
IPC: G01S1/72
Filed: 1921-01-28
Abstract: 170,544. Signal Ges. Oct. 16, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Detecting subaqueous sounds.-In apparatus for receiving subaqueous sound signals, and employing an electromagnetic detector, the detector is in the form of an oscillating structure comprising two masses connected by an elastic member such as a diaphragm, one of the masses being connected to the sound-receiving diaphragm, the other mass being free to oscillate. The receiving diaphragm may be aperiodic, or may have a natural frequency differing considerably from the signalling frequency, or it may be tuned to the frequency of the electromagnetic system. In this last case, the coupling of the diaphragm and detector gives rise to two resonance frequencies, one of which, preferably the lower, corresponds with the signalling frequency. This form is less responsive to low-frequency disturbances on the ship carrying the apparatus. The field magnet comprises a ring 4 having projections 6 which carry coils 5 connected to a telephone receiver 8. The armature 3 is mounted within the ring 4 by a diaphragm 7, which may be perforated, or by bands or threads. The armature 3 is connected to the sound-receiving diaphragm 2 which closes a casing 1. The diaphragm 2 may be plane as shown, or may have radial ribs which render it rigid except near its centre and periphery, or the central portion may be rigid so as to move bodily, and may be connected to or integral with the armature. The annular portion surrounding the central rigid part may have radial ribs. In another form, the diaphragm 2 decreases in thickness from the centre outwards, or has correspondingly tapered ribs.
